My tree (weeping Acacia) is about 1 yr. and 4 mo’s. old. It stands about 7 ft. tall but the base of the trunk is only a little larger than a pencil around.

You can plant it anytime. You will need to stake it to make sure it can withstand wind. This article will be useful: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm

Q. Control of acacia tree sucker

Acacia tree cut down 18 months ago. Tree stub was treated; nevertheless, we are getting suckers shooting up all over the garden. How can I eradicate this problem? This is in the south of France.

Cut the suckers and paint the fresh cuts with concentrated Round-Up. The tree will suck the Round-Up into its system and kill it. It may take a few applications, but will eventually kill the roots.

Q. Root system of Bailey Acacia

Our tree was planted as a young tree about 5 years ago. Our neighbor was told by her gardener that our tree killed her shrub that was about 30 years old. I believe it was a Photinia about 5 feet tall. Do the roots of our Acacia grow down deep or spread out?

The root system of the Acacia Tree is both shallow and runs deep.
They are know for their fast growing and invasive root system.
Whether or not the roots killed off another tree is difficult to say, but is possible.
Here are some articles with more information.

Q. Is an american Dogwood of the acacia family

I am trying to find common names for plants of acacia besides bay leaves. Acacia families that grow in the United States. For example, is an American Dogwood in the Acacia family?

American Dogwood is a member of Cornaceae, or the Dogwood family, not the acacia family.

Acacias are members of the Fabaceae or pea/legume family. They actually share the family with many plants that grow in gardens in the United States, including many types of beans, peas, and ornamental flowers such as sweet peas. There are also many wild relatives in the family.

The closest relative of Acacia that grows wild in the United States is probably the mesquite tree:

Q. purple acacia tree

I have a purple acacia tree. Looks sick. It was planted approx. 1 yr ago (maybe less), was growing fast, beautiful purplish/blush colored, feather-like leaves. Now it looks almost yellowish, doesn’t seem to be growing and just looks sad. Which makes me sad. Gets lots of afternoon sun, that area of my garden gets watered twice weekly. I have planted another purple acacia tree which is taking off beautifully. What is happening or what am I doing wrong?

Your acacia might need fertilizer or might need to be watered less often. These desert plants don't need much water. Here are some other possibilities:

Q. Acacia grown from seed

I have grown an acacia from seed brought back from South Africa by my daughter and son in law. I must have had the seeds perhaps ten years before I planted them. They were out there about 16 years ago. I have got it indoors in a 12-inch pot. Have recently cut the top out and it’s shooting again, now about 5 feet tall. Is there anything I can do to gain flowers? It’s in multi purpose compost, watered on occasions. It’s an impressive plant. I love it. It’s like a Venus fly trap, closing up at night. Is there anything else I can do to encourage flowers, please?

Increasing the level of light it receives could promote flowering. If possible, move it outside during the summer or during the days. Adding a source of phosphorus can also help promote blooms:
